after which the Master must send a NACK to end the operation. When the AT30TS750 receives
the NACK, it will release the SDA line so that the Master can send a STOP or repeated START
condition. If the Master does not send a NACK but instead sends an ACK after the lower byte of
the Temperature Register has been clocked out, then the device will repeat the sequence by
outputting new temperature data starting with the upper byte of the Temperature Register.
If 8-bit temperature resolution is satisfactory, then the lower byte of the Temperature Register
does not need to be read. In this case, the Master would send a NACK instead of an ACK after
the upper byte of the Temperature Register has been clocked out of the AT30TS750. When the
AT30TS750 receives the NACK, the device will know that it should not send out the lower byte of
the Temperature Register and will instead release the SDA line so the Master can send a STOP
or repeated START condition.
The Temperature Register defaults to 0000h after device power-up or reset; therefore, the system
should wait the maximum conversion time (tCONV) for the selected resolution before attempting to
read valid temperature data. If the device is configured to power-up in the Shutdown Mode, then
the device will make a single temperature measurement immediately after power-up so that valid
temperature data can be output from the Temperature Register after the maximum tCONV time.
Since the Temperature Register is a read-only register, any attempts to write to the register will
be ignored, and the device will subsequently respond by sending a NACK back to the Master for
any data bytes that are sent.
